NESTLINGS OF THE COMMON TERN (uPPER FIGURE) AND OF 

 THE RINGED PLOVER (LOWER FIGURE). 



Showing the close resemblance which obtains between the downy young and 

 their surroundings. The nest of the young terns contains an egg. Traces of 

 longitudinal stripes are to be seen in the young plovers ; in the terns they have 

 become broken up to form mottlings.
